RUBBER SHOE AND METHOD OF MAKING THE SAME.

Specification of Letters Patent.

Patented Sept. 7, 1920.

Application filed March 2c, 19 0. Serial No. 369,044.

. To all whom it may concern Be it known that I, GEORGE L. LAwRnnoE,Jr., a citizen of the United States, residing at elrose, in the countyof Middlesex and .State of Massachusetts, have invented certain new anduseful Improvements in Rubber Shoes and Methods of Making Same, of whichthe following is a full, clear, and exact description.

his invention relates to an improvement in turned edges on lumbermensrubber footwear, and is designed to provide .a neat and efiicient jointbetween the edges of the quarters and the edges of the tongue, as wellas between the edges of the quarters and the vamp and the method ofproducing the joints.

This is accomplished by folding over the top and front edges of therubberized fabric quarters,'which are provided on their outer faces witha comparatively thick coating of high-grade rubber, which high-graderubber is disposed on' the inner sides of the quarters to the width ofthe folds. This enables a good, waterproofed bond to be formed betweenthe quarters and the edges of the tongue, and between the quarters andthe vamp.

The precise nature of my invention will be best understood. by referenceto the accompanying drawings, it being obvious, however, that changesmay be made in the form anddetails of construction of the shoe, withoutdeparting from the spirit and scope of my invention as defined in theappended claims.

In the drawings,

Figure l is an inside face view of two quarters after they have beenconnected to each other at the back.

Fig. 2 is a detailed sectional line 22 of Fig. 1, and

Fig. 3 is a perspective view of one form of shoe made in accordance withmy invention.

in these drawings, the reference character quarters, 4 the tongue two ofits edges to the view on the which is secured at edges of the quarters3, which is also secured to the thereof.

The lower edges of the quarters of the shoe are also secured to the vamp5 at the point 6.

In the manufacture of shoes in accordvamp 5 at the lower edge ance withmy invention, the fabric from which the quarters are died is provided onits outer face with a relatively thick coating 7 of good rubber. The topand vertical edges ofthe quarters are then folded upon themselves asindicated at 8 in, Fig. 1, and the two quarters are connected to eachother along their back edges as indicated at 9 to form the center oftheback of the shoe. In Fig. 1 I have indicated at 8 a portion of theedge before it has been folded upon itself. After the, quarters aresecured to each other, a tongue-forming portion is connected to each ofthe vertical edges of the quarters, so that the inner face of saidtongue-forming portions engages the surface of high-grade rubber 7 whichhas been folded back upon itself, as clearly indicated in Fig. 2.Eyelets 10 may then be passed through the quarters and thetongue-forming portions along both the outer edges of the connectedquarters, as indicated at the right hand side of Fig. 1, but if desired,buckle straps may be secured between the inturned edges of the quartersand the edges of the tongue-forming portions.

The shoe is then built up in the usual mannner, and the folded edges ofthe quarters are connected to the vamp at the points 6, and the shoesare then vulcanized.

By folding over the edges of the quarters. I am enabled to provide agood quality of rubber at the seams to form the joint between the edgesof the quarters and the various members to which they are secured.

The advantages of my invention result from the provision of a vulcanizedshoe having rubberized fabric quarters whose seaming fabric edges areturned upon themselves, to bring the good facing of rubber on theexterior thereof into contact with the other members to whichthequarters are to be secured along the joints, and the method of formingthe joint.

Having thus described my invention, what I claim and desire to protectby Letters Patent is:

l. A rubber shoe having rubberized fabric quarters vulcanized at theirfront edges to the edges of the tongue and the vamp, said quartershaving the fabric and rubber along their outer front edges folded uponthemselves to bring the outer rubber faces of the quarters into contactwith the edge portions of the tongue.
